Claims

[Scope of utility model registration request]

A joint body that is bent in an L shape, has a passage inside thereof, and is open at one end of the joint body that is open at both ends, and is provided with a connecting mechanism to which a connecting member forming the end of the flexible gas pipe can be connected. A locking recess for the connection member is formed at the opening on the combustion equipment connection side at the other end, and a locking ring with a diameter larger than the inner diameter of the locking recess is provided at a position close to the opening on the inner periphery of the locking recess. In addition to this, the locking groove is recessed in an annular shape, and the connecting member to be inserted into the locking recess is a tubular body with a flange at one end, and a ring is provided at a position adjacent to the flange on the outer periphery of the tubular body. A substantially C-shaped retaining ring made of an elastic material can be fitted into the annular groove for use, and an O
An annular concave groove for a ring is provided so that an O-ring can be fitted therein, and an insertion hole is opened in the front face with a diameter through which a part other than the flange of the connecting member can be inserted, and the diameter is larger in the depth direction. A union nut is formed in which a stepped part for transition is formed as a flange engaging part, and a threaded hole having a female thread into which a male thread of a gas intake port of a combustion appliance can be screwed is provided on the inner periphery of a large diameter, A joint fitting for connecting a gas supply pipe and a combustor, characterized in that it is made up of a combination of the union nut, the joint body, the connecting member, the retaining ring, and the O-ring.
